Application May 27; 1946,'Serial No. 672,599 r and particularly tolubricant discharge" nozzles or couplers which may be adjusted angularlyand locked in position.

nHeretofo re, angularly adjustable couplings for 7 lubricating deviceshave been provided with a releasing mechanism which protruded from theside of the coupling. Ihe purpose of providing an angularly adjustablecoupling is to reach fittingswhich are frequently so located that accessthereto is rendered difiicult by parts of the machine, it beingsometimes impossible to reach the fitting with a straight nozzle orcoupling. However, with the aforesaid protruding releasing device, itwas 'ofttimes difiicult or impossible .to reach the fitting even thoughthe coupling was adjustable angularly.

'It-is, therefore, an important object of the in- I .9 Claims. (01. 285961) This invention relatesto a lubricating device vention to provide anangularly adjustable lubricant coupling or nozzle which is free ofprotruding; parts.

wItis also an object of the invention to provide anqangularly adjustablelubricant coupling. or nozzle in which the mechanism for releasing andthe locking mechanism for locking the coupling or nozzle in variouspositions is contained ennozzle.

i It is another object of the invention to provide an angularlyadjustable lubricant coupling or nozzle which is free to swivel or islocked in pending uponthe wishes of the operator.

,;It iSJ Sl7i11 another object of the invention to provide an angularlyadjustable lubricant coupling or nozzlewhich does not automaticallyreturn tothe locked position when moved to. a swivellingrposition but,rather, requires intene tional re-locking .by the opera-tor whendesired.

. It is-another object of the invention to provide a releasing device ofthe character described wherein the movable parts are always tightlyretained in their proper relationship.

It is a further object of the invention to provide alarge number ofangular adjustments for a lubricating nozzle Still another object of theinvention is to simplify theangularly adjustable lubricant coupling andthe releasing and locking mechanism therefor. 1

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevicev whereby the objects contemplated are attained, as herei aitermore hilly set birth.

The conduit member H iscon-nected at its inner end to a plunger l3having a passage [4 centrally thereof communicating with a passage H5 inthe threaded rigid conduit II. The rigid conduit H and plunger l3 arepreferably sec" l'zd together by cooperating threads IS. a beveledsurface I! on .the plunger 13 providing a stop for the coupling memberH. T

The passage M in plunger. I3 is reduced at l8 line 5- 5 andcommunicateswith a passage l9 ina resi1ient gasket 2i with a passage 23in a swivelmeinher 20 of an angularly adjustable speed coupling,generally indicated at 22. The resilient gasket I9 is held in positionby a plate 24' pressed by a end wall'ZB of plunger. I 3.

The passage 23 in swivel memberZD communicates with a cylindricalmember, 21 disposed at an angleof approximately 45 from the horizontalaxis of the plunger l3 and swivel member 20 so that, when the swivelmember 26 is swung about its axis in the manner hereinafter described, alarge number of positions are obtainable, as shown in Figure 2. Thecylindrical member 21 has a passage 28 therein communicating with ahollow bushing 29 extending through a plate 3 and a, resilient gasket32. The

cylindric lmemberil is 9pm a 53 9; th re:

ception of a lubricating fitting (not shown) which is held against thehollow bushing 29 by jaws thus placing the passage 28 in communicationwith the fitting. Lubricant, therefore, may pass freely from thethreaded inlet E2 to the fitting. A coil spring 35. engages a shoulder35 in passage 2'8 andforces the plate 35 against gaslzet 32, anapertured transverse wall 3? in the cylindrical member 2'? engaging theopposite side of gasket 32.

The internal construction of the speed coupling member 22 is covered'bythe patent to Nielson No. 2,263,850, assigned to The Arc EquipmentCorporation.

In accordance with the present invention, the swivel portion 29 of thespeed coupling is secured by cooperating threads 38 to a sleeve member39 encompassing the plunger l3 and having an annular flanged portion 4|which provides shoulders 42 and 43 thereon. The shoulder 43 engages withone side 44 of an abutment 45 on the plunger I3. A shoulder 46 on thethreaded portion of the swivel member 29 engages with an opposite side41 of abutment 45.

The end of the sleeve member 39 adjacent swivel 20 is provided with anangular or serrated surface 48 shown herein as hexagonal in shape. Aslidable cupshaped member 49 encompasses the sleeve member 39 andplunger I3 and is provided at the end thereof adjacent the swivel 29with a serrated surface 5|, shown herein as consisting of twelvenotches, which cooperates or meshes with the hexagonal surface 48 onsleeve member 39 to prevent turning of the speed coupling 22 when thesesurfaces are in engagement. I

End 59 of the plunger [3 adjacent the threaded coupling I2 is' notcompletely circular in cross section, but is provided with flat surfaces5|. The cup-shaped member 49 is provided with an aperture 52 in thebottom thereof, through which the plunger is slidably extends, and saidaperture 52 is shaped to conform tothe end 50 of the plunger.

A resilient snap ring 53 is retained in a recess 54 in the sleeve 39 andfrictionally engages the inner surface of the cup-shaped member 49. Ashoulder 55 on inlet coupling [2 engages the cup-shaped member 49 asshown in Figure 4 to limit the relative movement of plunger l3 and itsassociated movable parts with respect to sleeve Operation After theinlet coupling I I has been secured to a source of lubricant underpressure, the speed coupling 22 may be swung to any of twelve angularpositions inthe following manner, it being understood that this numberof positions is used by way of example. 7

The operator moves the sleeve 49 to the left, as shown in Figure 4, thuswithdrawing the teeth 5| from the teeth 48. The shoulder 55 then abutsagainst member 49 and prevents further movement of the parts.

It is then possible to rotate coupling member 22 and sleeve 39 to anydesired position, after which the sleeve 49 is forced .to the right inthe drawings and the parts again engage, as shown, for example, inFigures 3 and 6. The flat portions 5! of plunger I3 prevent thecup-shaped member 49 from rotating with sleeve 39. The resilient snapring 53 provides sufficient frictional resistance to preventunintentional relative movement between sleeve 39 and cup-shaped member49. l I 1 It will be noted that when the sleeve 49 is moved to the left,it will stay in that position until deliberately changed, because of thefrictional engagement of ring 53 with sleeve 49. Therefore, the teeth 48.and 5i are disengaged and the member 29 is free to swivel in anydirection. If the operator wishes to lockthe member '20, then the sleeve49 is moved to engage the teeth 48 and 5!. So far as I am aware, allprior adjustable lubricant couplers were automatically returned to thelocked position when released by the operator, usually by a spring, andfree swivelling was impossible.

From the foregoing it will be apparent that the coupling has noprotruding parts to prevent access to the lubricant fittings, and thatthe release and locking portions of the angular adjustment are containedentirely within the confines of the coupling body.

Some changes may be made in the construction and arrangement of theparts of my lubricating device without departing from the real spiritand purpose of my invention, and it is my intention to cover by myclaims any modified forms of structure or use of mechanical equivalentswhich may be reasonably included within their scope without sacrificingany of the advantages thereof.
